I've used my no sniveller down into the 20s with no problem. I really like how I can wear it around camp with the head hole. I ordered the long size so I can pull it up over my head when the temperature drops below freezing.

Hello Joe G.i have used the hudson river, a no sniveller minus the hole. the two Jacks are the only commercial enterprise who make one single piece of gear that can be used for:a closed foot, top quilt on the ground or in a hammocka hammock underquilt a flat blanketa serape/ponchothe versatility of the No Sniveller cannot be beaten. however, unless you plan on using it for temps from 30-60° you might find it a bit "too" versatile. I used a Highlite and found the small zipper to be of little use in temps about 45° and above. I sold it in favor of the JrB quilt. I found that the JrB quilt although a very nice piece of gear, has a width of 48" and that makes for a BIG footbox. It was imho a bit too big for my feet and all that dead space = wasted energy to heat it. Sold it in favor of a DIY quilt. I would narrow a search for good prices between the Summerlite and the Ultra 20. If all you want is a quilt for ground sleeping and you want the weight savings, the Ultra 20 is terrific. If you ever plan on using the No Sniveller in humid, warm camps or as a hammock underquilt, it is the BOMBIt would be easier to narrow a specific model for you if we were told exactly what conditions you expect to endure :) mike* i used the Hudson River quilt down to 30 without any cold spots, wearing only hiking pants and t-shirt. only sold it in favor of a momentum and down quilt project that turned out well.

I just got an ultra 20 for winter camping in the PNW. have only tested it in the back yard so far, but I was a little too warm with my cocoon parka when temp was around freezing. I'm eager to really put it to the test but it seems like a great quilt for a good price.

Make sure its girth will work for you at the shoulders. When I'm on my side I sometimes wish there was more material for tucking under me. One option here is to consider the Jrb 'quilt wings'. I believe the Ultra is wider.

As far as the Golite Ultra 20...I had it down to exactly 20 degrees at 5500 feet with significant wind. I was sleeping inside a MLD bivy under a ID silponcho tarp. As far as clothing goes, I was wearing baselayer with a light fleece cap and my montbell UL down inner. Ground insulation was light, 3/8" GG thinlight trimmed to 38" long (3.4 oz).

I slept fine and I tend to get cold. I think if the temp dropped much more I would need a few more extra garments to stay warm. I'd say that is pretty good for 18.65 oz (i dropped the under straps) and <$200 on sale.
